Used primarily as a surface modifier in the production of silica-based materials, enhancing adhesion and compatibility in composite materials. It is also employed in the synthesis of organic-inorganic hybrid materials, where it acts as a coupling agent to improve the interface between organic polymers and inorganic fillers. In coatings, it provides water repellency and durability, making it suitable for protective layers on various substrates. Additionally, it finds application in the preparation of silylating agents for chemical derivatization in analytical chemistry, aiding in the analysis of complex molecules. Its role in modifying surfaces for biomedical applications, such as functionalizing medical devices, is also noteworthy.
